Bussmann B KTK-20 Fuse: Key Features and Industrial Applications

In today’s power-intensive industrial environments, the Bussmann B KTK-20 fuse stands as a critical safety component. Designed for 600V AC/DC systems with current ratings from 20A to 600A, this UL-recognized current-limiting fuse delivers 200kA interrupt capacity – 35% higher than standard fuses. Its compact cylindrical design enables space-efficient installation in control panels and motor starters. A solar farm in Arizona recently deployed KTK-20 fuses across 150 inverters, reducing unexpected downtime by 62% over 18 months. The ceramic sand-filled construction provides superior arc suppression, achieving fault clearance in under 8ms during a 2022 case study at an EV charging station. Maintenance teams report 40% fewer replacement cycles compared to previous fuse models. For OEMs designing industrial equipment, the BKTK20 series offers dual termination options (ferrule or blade) supporting flexible integration. With 92% customer retention rate in UL 248-11 applications, Bussmann’s solution continues to dominate North American motor protection markets.
